MANUFACTURE OF PAINTS AND PRINTING-COLORS.

No Drawing.

To all whom it may concern:

Be it known that I, NrcoLAI WASILIEVITCH TURKIN, a subject of the Czarof Russia, residing at Moscow, Russia, have invented certain new anduseful Improvements in the Manufacture of Paints and Printing-Colors, ofwhich the following is a specification.

This invention relates to the manufacture of paints and printing colorsfrom coloring matters produced by the process described in thespecification of my co-pending patent application Serial No. 811,173,filed January 9th, 1914.

The process referred to above for the production of coloring matters ordye stuffs suitable for painting, printing, etc., consists broadly indissolving any desired pigment in a carrier so as to produce colloidalsolutions of the pigment therein. The carrier has for its mainconstituent alizarin oil, and this is incorporated by heating with oneor several other substances, such for example as basic aluminiumacetate, salts of alkaline earth metals, naphthalene, fats or oils,etc., so as to produce a composition insoluble in water.

According to the present invention the composition of matter for use asa paint is obtained by adding to a coloring matter obtained by theprocess described in the specification of my co-pending patentapplication Serial No. 811,173 a varnish to act as a vehicle or carrierfor the same, the said varnish being produced by heating together resinand an animal fatty substance and dissolving the product obtainedthereby in a suitable liquid solvent of an aromatic series, viz: toluol,oil of turpentine, or the distillation produts from naphtha, coal orresin and by the term liquid solvent as used herein and in the claims, Iintend to cover only these substances.

When the paint is intended for use as an artists color, the compositionof the varnish is somewhat modified in that the solid resins used invarnishes for producing common paint for ordinary painting purposes arereplaced by easily liquefied resins, such for example as balsams.

A further feature of this invention is the manufacture of colorsfor'printing purposes, for which purpose the pigment is incorporatedwith alizarin oil, either or both basic aluminium acetateand or a saltof a metal of the alkaline earths or alkalis, and a mixture of an animalfatty substance and naph- Specification of Letters Patent.

thalene, and in addition with large quantities of mixtures of resins anda small quantity of glucose if desired, the Whole mass being heateduntil it is of a consistency to solidify on cooling; the product thusobtained is then boiled with a thick fluid resin mixture prepared byboiling animal fat and resin with a suitable solvent, such for exampleas alcohol.

Throughout this specification and claims the word naphthalene is used todenote both naphthalene and its derivatives, and the term animal fattysubstance is used to denote either animal fats or oils.

In order to dilute the coloring matters prepared as described in thespecification of my aforesaid patent application, to any degree requiredaccording to the use for which they are intended, there must be used asdiluents varnishes of a special kind, namely those containing resin andfish-oil dissolved in naphthalene or in the products of resin,

coal and naphtha distillation, such for example as oil of turpentine,toluol, benzol, and creosote.

By using such varnishes, it is possible to dissolve completely thecoloring matters prepared in the above mentioned manner, so that acoloring matter or dye-stuff is again obtained, which, like the initialcoloring matter contains pigment in solution, and whenever a thin layerof the pigment carrier is removed by solution, there is simultaneouslyremoved a corresponding portion of the dissolved pigment.

The addition of such a varnish imparts to the pigment a slight capacityto diffuse between the adjoining color coatings. This power of diffusioncan be increased to any desired extent by the application of essentialoils, such as for example aniseed oil, lemonoil and the like, so thatthe limit or separation line between the adjoining color layers orbodies is wiped out; conversely, the power of diffusion can be destroyedby providing the adjoining color layers or color bodies on the surfacewith a coating of alizarin (Turkey red) oil and ammonia.

In carrying this invention into practical efl'ect the coloring mattersaremanufactured as described in the specification of my patentapplication hereinbefore referred to.

A suitable diluent or varnish for the coloring substance is obtained asfollows :2.5 kg. fish (train) oil, 9 kg. shellac or, as s preferred, 7.5kg. powdered copal resin (Angola) and a small quantity, for instance 1kg. turpentine oil are well mixed together and boiled, the mass beingthereupon poured while still warm into about 30 kg. toluol or 10 kg.turpentine oil and thoroughly stirred, until a clear solution isproduced. Into this varnish is introduced a suitable quantity of thecoloring matter obtained in the manner hereinbefore referred to, untilthe desired degree of spreading and covering capacity is obtained.

For artists colors the same coloring matter as is employed for ordinarypaint can be used, but a slightly different varnish is solved in asuitable quantity of toluol or some other product of distillation ofnaphtha, coal or resin.

The following is an example of the manufacture of a red color suitablefor printing purposes. First of all there are prepared three mixturesconsisting of :-1. 100 gms. basic aluminium acetate and 200 gms.alizarin (Turkey red) oil. 2. 10 gms. Biebrich scarlet and 100 gms.alizarin (Turkey red) oil. 3. 20 gms. naphthalene and 20 gms. fish(train) oil. These three mixtures are combined together, and a mixtureof resins, consisting of 50 gms. Canada balsam, 250 gms. Venetianturpentine, 100 gms. copal resin, 50 gms. pine resin, 25 gms. elemiresin, 50 gms. shellac is added to it, with constant stirring andheating. Moreover, 25 gms. glucose, previously mixed if desired withpowdered resins, are added to the mass. The mass is again boiled, untilit becomes solid on cooling. I/Vith this coloring mass is combined athick fluid resin mixture previously prepared by mixing 125 gms. fish(train) oil, 650 gms. copal resin with 225 gms. spirits of wine (95%) orsome other (preliminary) solvent, and boiling the mixture in question.In the event of the mass being too solid for treatment, some solvent,such as for instance toluol, can be added to it, until it acquires thedesired consistency. In the same Way any desired color pigment can beintroduced into the same or asimilar carrier substance.

Throughout this specification, alizarin oil is used to denote theneutralized products obtained by treating with sulfuric acid not onlyolive oil, but also other oils, such for example a castor oil, cottonseed oil and other oils containing glycerids of palmitic acid, oleicacid, etc.

In order to prepare plates for printing purposes, the colors aretransferred to the plate, according to the desired pattern by means of abrush or the like, care being taken to avoid overlapping of the edges ofthe various color zones, and subsequently the plates are dried, ifdesired by heat. Another method consists in forming the printing blockof small bars of the various col oring substances required 'to build upthe pattern.

In printing from plates or blocks prepared as above described thesurface of the same is moistened with a color solvent prepared asfollows 2-75 gms. spirits of Wine (95%), 155 gms. spirits of lavender,40 gms. alizarin (Turkey red) oil, 150 gms. methyl alcohol, 120 gms.toluol, 10 gms. xylol, 15 gms. paraffin in the form of a solution inxylol and of the consistency of milk, 190 gms. glacial acetic acid, 40gms. petroleum ether, 25 gems. sulfuric ether, 50 gms. acetic ether, 10gms. creosote, 75 gms. ammonia 15 gms. of an alcohol solution, of milkconsistency, of equal quantities of copal resin and fish (train) oil,are all boiled to-, gether.

Instead of moistening the plates or blocks, the surface to be printed oncan be moistened with the color solvent, whereby the printing surfacesare indirectly moistened.

The proportions of mixtures of the varnishes and of the coloring matterswith which they are mixed are only given in the specification by way ofexample, and may be varied according to the nature of the product, it isdesired to obtain.
